Abstract
An address frequency operation unit counts frequencies of occurrences of addresses output by an address conversion unit, and a CPUrewrites an address conversion table in the address conversion unitbased on a comparison between the counted result and a threshold value. When the frequency of the address is lower than the threshold value, the frequency of occurrence of an output address is increased by increasing the number of input addresses corresponding to one output address. Also, distortion in an output signal which is fed back is detected and the address conversion table is rewritten so that the distortion is decreased.
